Please explain fault code 1-2-1?

Thanks for your response. I cleared the fault codes (both 435 and 121) without changing O2 sensor. If the check engine light comes back on, I will have the sensor replaced.

Since I have no idea what the MAF sensor is for and of course don't know where it locates, I appreciate if you could describe in detail where it is. Thanks in advance.
